German scientists have found out that administration of the AstraZeneca vaccine could potentially produce antibodies that would in turn stimulate formation of blood clots in “rare” cases as the WHO sees no such “causal” link. A research team from Germany’s Greifswald University Hospital have discovered a mechanism that could lead to the development of sinus or cerebral vein thrombosis in patients who received the AstraZeneca jab.
The team received six blood samples of people who suffered from thrombosis after taking the jab. The samples were provided by the Paul Ehrlich Institute – the body responsible for approval and monitoring of all vaccines in Germany.
Following the analysis, the Greifswald researchers found out that an immune response to the vaccine could involve formation of antibodies that are normally formed only when an organism needs to heal a wound through blood coagulation, the German broadcaster NDR reported. These antibodies then “activate” the platelets and could stimulate the formation of blood clots, particularly in the brain’s venous sinuses.
he team’s conclusions, which are yet to be published in any scientific journal, were then shared by the German Research Association for Thrombosis and Hemostasis (GTH), which issued a new guideline for patients receiving the vaccine.
